Two quotes from the NYT article that I feel are important to have in the back of your head when you plan your fake accounts:

Now, other intelligence agencies will be able to search directly through raw repositories of communications intercepted by the N.S.A. and then apply such rules for “minimizing” privacy intrusions.

But Patrick Toomey, a lawyer for the American Civil Liberties Union, called the move an erosion of rules intended to protect the privacy of Americans when their messages are caught by the N.S.A.’s powerful global collection methods. He noted that domestic internet data was often routed or stored abroad, where it may get vacuumed up without court oversight.

Let's say CBP get's a tool in a couple of months that let's their border agent search up any passenger through the NSA raw data. That search may then produce your real accounts. Let's say they do this before questioning you, and you then provide them with your fake accounts, that will not look good.
